RIVET-SETTING MACHINE.

Specification of Letters Patent.

Application filed February 15, 1915. Serial No. 8,161.

To all whom it may concern:

Be it known that I, ARTHUR R. HAvnNEn, a citizen of the United States, residing at VValtham, in the county of MiddleseX and State of Massachusetts, have invented new and useful Improvements in Rivet-Setting Machines, of which the following is a specification.

This invention relates to a rivet setting machine and is particularly adapted for setting rivet spots, that is, rivets having two prongs.

The machine is an improvement upon the machine for which United States Letters Patent were issued to me on February 27, 1912, No. 1,018,? 61, to which reference may be had for that portion of the mechanism which imparts motion to the main driving lever of the mechanism embodying this invention hereafter set forth in the specification.

The invention consists in the combination and arrangement of parts set forth in the specification and particularly pointed out in the claims thereof.

Referring to the drawings: Figure 1 is a front elevation of my improved rivet setting machine. Fig. 2 is a side elevation of the same. Fig. 3 is a detail View, partly in section, illustrating a portion of the hopper mechanism. Fig. 4 is a sectional elevation taken on line 4-4 of Fig. 1, the column in Figs. 1, 2 and 4 being broken away to save space in the drawings. Fig. 5 is a sectional plan taken on line 5- -5 of Fig. 4. Fig. 6 is an enlarged sectional plan taken on line 6-6 of Fig. 1. Fig. 7 is an enlarged vertical section showing the rivet holder and guide, together with the anvil, the parts being in position to start the operation of driving a rivet downwardly into the material in which it is to be riveted. Fig. 8 is a view similar to Fig. 7 with the parts brought together and the rivet set in the material. Fig. 9 is a detail front elevation of one of the pawl carriers. Fig. 10 is a plan of said pawl carrier. Fig. 11 is a detail front elevation of another pawl carrier. Fig. 12 is a detail plan of the pawl carrier illustrated in Fig. 11.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 15 is a column upon which is rotatably mounted a carrier sleeve 16 which is locked in position by a latch. 1'7

ranged to enter a notch 18 in a flange 19 on the carrier sleeve 16, said sleeve thus being locked to the column 15 when the mechan1sm for setting the rivet is in operation. The sleeve 16 is arranged to have a plurality of rivet setting mechanisms fastened thereto, only one of said mechanisms being shown in the drawings, however. The manner of attaching the machines to the sleeve is illustrated in said Letters Patent, and the frames upon which said'mechanisms are mounted are fastened to the sleeves on the different flattened portions 20.

21 is the frame of one ofthe rivet setting mechanisms. The rivets are placed in mass in a hopper 22 which has a rotary member 23 therein provided with flexible fingers 24 and constituting, as a whole, a species of brush whereby the rivets are moved around in the hopper 22 and fed down a raceway 25. The lower end of the raceway 25 terminates adjacent to a rivet carrier 26 which is made in two parts 27 and 28 arranged above and slidable upon a stationary rivet guide 29 which constitutes a work-abutment. Said parts 27 and 28 are movable toward and away from each other and are moved toward each other by a spring 30 which engages said parts and is fastened by a screw 31 to the stationary guide 29.

The guide 29 is provided with two upwardly extending arms 32 which are slidable for adjustment in ways 33 provided in a bracket 34 forming a part of the frame of the machine. The lower end of the raceway 25 is fastened to said rivet guide 29.

A plunger 35 for driving the rivets through the material, in order to clench the same, is slidably mounted in the frame of the machine and has a collar 36 fast thereto which is connected by a pin 37 to a lever 38. The lever 38 is fastened to a rock-shaft 39 journaled to rock on the frame of the ma chine and is connected at its rear end by a link 40 to the main operating lever 41, said main operating lever being pivoted by a shaft 42 to the frame of the machine. It

will be evident that by rocking the lever 41 a rocking motion will be imparted to the lever 38 and by said lever a reciprocatory motion will be imparted to the plunger 35.

An anvil 43 is detachably fastened to the upper end of a slide 44 to which a reclprocatory motion is imparted by a lever 45 connected by a link 46 to another lever 47 Patented July 25, 1916.

which has a rod 48 pivoted thereto at 49. The rod 48 is slidable in ears 50 formed upon an arm 51 which at its upper end is pivoted at 52 to the lever 41'. A collar 53 has screw-threaded engagement with the rod 48 and is locked thereto by means of a setscrew 54. A spring 55 is interposed between the collor 53 and the lower ear 50, while'another collar-56 is fastened to the rod 48 and forms a stop to limit the distance to which the rod 48 can be moved upwardly in its bearings on the arm 51. i

A spring 57 connects the lever 41 to the casing of the hopper 22 and when the rivet setting mechanism is in a state of rest the main driving lever 41 will be in the position illustrated in the drawings, especially re ferring to Fig. 4, wherein it will be seen that the hooked end 58 of a vertical rod 59 projects over a roll 60 journaled upon the lever 41 and forming, in effect, apart thereof. The upward movement of the rod 59 is limited by a bracket 61 having a curved under face 62 against which the upper curved face of the hook 58 abuts. The rod 59 is moved downwardly by means of suitablemechanism such as that described and illustrated in said Letters Patent, and the hooked end 58 engaging the roll 60 operates the lever 41 to impart a downward movement to the plunger 35 and an upward movement to the anvil '43, the upward movement of the anvil 43 being communicated thereto through the arm 51, rod 48, lever 47, link 46, lever 45 and slide 44.

'The rotary member 23 of the hopper 22 i is fast to a shaft 63 and to the lower "end of said shaft a gear 64 is fastened which meshes into another gear 65 fast to a shaft 66. Two ratchets 67 and 68 are fastened to the shaft 66 and are rotated by means of pawls 69 and 70, respectively, said pawls being pivoted upon pawl carriers 71 and 72. The

pawl carriers 71 and 72 are pivoted upon the f shaft 66and have sliding engagement with oppositelydisposed pins 73 and 74 which are fastened to a slide 75, the lower end of which'is pivoted at 76to an arm 77 fast tothe rock-shaft 39. r 1 7 It will be seen that the teeth on the two separate ratchets 67 and 68 are cut in the same direction and, therefore, as said ratchets are both fastened to the shaft 66, it is evident that said ratc'hets 67 and 68 might be made in one piece. In the operation of the pawls and their carriers when the slide 75 is moved upwardly the pawl will operate to rotate the shaft 66 through its ratchet 68 and when the slide is moved downwardly the pawl 69 will operate to rotate the shaft 66 through its ratchet 67 and thus a practically continuous movement is imparted to the rotary member 23 as the same is rotated both during the upward and downward movement of the rod 59,

slide 75, whereby the pawl carriers 71 and 72 will be rocked upon the shaft 66 and the pawls 69 and 7 0 will impart an intermittent rotary motion to said shaft 66 through their respective ratchets 67 and 68 I and thus, through the gearing 65 and 64, the shaft 63 will be rotated, together with the member 23 fast thereto, thus rotating the. fingers 24 around the interior of the hopper casing and brushing the rivets located in the hopper into the raceway 25. i

The hopper mechanism herein shown and described ,is made the subject-matter of a separate application filed by. me of even date herewith.

The general operation of the mechanism hereinbefore specifically and to some extent in general described is as follows: The operator places the material 78 in which the rivet 79 is to be driven and clenched, upon the anvil 43, the parts being in the relative positions illustrated in the drawings. He then starts the machine in operation by depressing a treadle, as shown and described in said Letters Patent, thus pulling the rod 59 downwardly. The hooked end 58 of said rod, as hereinbefore described, will then actuate the lever 41 and through the mechanisms hereinbefore described the plunger 35 will move; downwardly, the anvil 43 will move upwardly and the rotary member 23 down the raceway. As the plunger 35 descends it engages the head of the rivet 79 located at that time in the rivet carrier, as illustrated in Fig. 7. The material 78 will in the hopper will be rotated to feed rivets be carried upwardly by the anvil 43 until I it is brought into contact with the rivet guide 29 which constitutesan abutment for said material. The plunger continuing its downward descent will push the rivet through between the partsf27 and 28 of the rivet carrier 26, said parts moving away from each other to allow the rivet to pass therebetween and said rivet will then be guided through the tubular portion of the rivet guide 29 until its prongs engage the material '78 and are driven through said material and clenched in said material by reason of engagement with the anvil 43, the upper surface of which is so formed as to cause said prongs to be turned and clenched in a manner'well known to thosefskilledin this art. If the material 78 varies inthickness, then thespring 55 will yield after said material has been brought firmly into con-n means of the collar 53 which is locked in position by means of the set-screw 54:. It will be evident that if the anvil 43 is arranged to move within a certain distance of the under face of the rivet guide 29 without compression of the spring 55, thus allowing for a certain thickness of material, if a thicker piece of material is placed between the anvil and the rivet guide, when said thicker material contacts with the under side of the rivet guide 29 a further movement on the part of the lever 41 will move the arm 51 upwardly and this will result in causing said arm to slide upon the rod a8 and will compress the spring 55 to a slight extent.

After the rivet has been set in the material the different parts of the machine assume the relative positions illustrated in the drawings and the machine stops. The operator then moves the material to another position and the operation hereinbefore described to set another rivet in said material is repeated.

Having thus described my invention, what I claim and desire by Letters Patent to secure is:
